Abstract
Oil bodies (OBs) function as organelles that store lipids in plant seeds. An oil body (OB) is encased by a membrane composed of proteins (e.g., oleosins, caleosins, and steroleosins) and a phospholipid monolayer. The distinctive protein-phospholipid membrane architecture of OBs imparts exceptional stability even in extreme environments, thereby sparking increasing interest in their structure and properties. However, a comprehensive understanding of the structure-activity relationships determining the stability and properties of oil bodies requires a more profound exploration of the associated membrane proteins, an aspect that remains relatively unexplored. In this review, we aim to summarize and discuss the structural attributes, biological functions, and properties of OB membrane proteins. From a commercial perspective, an in-depth understanding of the structural and functional properties of OBs is important for the expansion of their applications by producing artificial oil bodies (AOB). Besides exploring their structural intricacies, we describe various methods that are used for purifying and isolating OB membrane proteins. These insights may provide a foundational framework for the practical utilization of OB membrane proteins in diverse applications within the realm of AOB technology, including biological and probiotic delivery, protein purification, enzyme immobilization, astringency detection, and antibody production.

Abstract
The continuing emergence of variants of the SARS-CoV-2 virus requires the development of modular molecular therapies. Here, we engineered a recombinant amphiphilic protein, oleosin, to spontaneously self-assemble into multivalent micellar nanostructures which can block the Spike S1 protein of SARS-CoV-2 pseudoviruses (PVs). Short recombinant proteins like oleosin can be formulated more easily than antibodies and can be functionalized with precision through genetic engineering. We cloned S1-binding mini-protein genes called LCBx, previously designed by David Baker's laboratory (UW Seattle), to the N-terminus of oleosin, expressing Oleo-LCBx proteins in E. coli. These proteins largely formed 10-100 nm micelles as verified by dynamic light scattering. Two proteins, Oleo-LCB1 and Oleo-LCB3, were seen to completely and irreversibly block transduction by both wild-type and delta variant PVs into 293T-hsACE2 cells at 10 μM. Presented in multivalent micelles, these proteins reduced transduction by PVs down to a functional protein concentration of 5 nM. Additionally, Oleo-LCB1 micelles outperformed corresponding synthetic LCB1 mini-proteins in reducing transduction by PVs. Tunable aqueous solubility of recombinant oleosin allowed incorporation of peptides/mini-proteins at high concentrations within micelles, thus enhancing drug loading. To validate the potential multifunctionality of the micelles, we showed that certain combinations of Oleo-LCB1 and Oleo-LCB3 performed much better than the individual proteins at the same concentration. These micelles, which we showed to be non-toxic to human cells, are thus a promising step toward the design of modular, multifunctional therapeutics that could bind to and inactivate multiple receptors and proteins necessary for the infection of the SARS-CoV-2 virus.

Abstract
Self-assembling proteins are valuable building blocks for constructing drug nanocarriers due to their self-assembly behavior, monodispersity, biocompatibility, and biodegradability. Genetic and chemical modifications allow for modular design of protein nanocarriers with effective drug encapsulation, targetability, stimuli responsiveness, and in vivo half-life. Protein nanocarriers have been developed to deliver various therapeutic molecules including small molecules, proteins, and nucleic acids with proven in vitro and in vivo efficacy. This article reviews recent advances in protein nanocarriers that are not derived from natural protein nanostructures, such as protein cages or virus like particles. The protein nanocarriers described here are self-assembled from rationally or de novo designed recombinant proteins, as well as recombinant proteins complexed with other biomolecules, presenting properties that are unique from those of natural protein carriers. Design, functionalization, and therapeutic application of protein nanocarriers will be discussed.

Abstract
Delivery of functional proteins into cells may help us understand how specific protein influences cell behavior as well as treat diseases caused by protein deficiency or loss-of-function mutations. However, protein cannot enter cells by diffusion. In this work, a novel cell biology tool for delivering recombinant proteins into mammalian cells was developed. We hijacked the intracellular transport routes used by the cholera toxin and took advantage of recent development on split intein that is compatible with denatured conditions and shows an exceptional splicing activity to deliver a protein of interest into mammalian cells. Here, we used green fluorescent protein and apoptin as proofs-of-concept. The results demonstrate that the cholera toxin B subunit alone could deliver other recombinant proteins into cells through either covalent conjugation or noncovalent interaction. Our method offers more than 10-fold better delivery efficiency than the tat cell-penetrating peptide and is selective for ganglioside-rich cells. This study adds a useful tool to the receptor-mediated intracellular targeting toolkit and opens possibility for the selective delivery of therapeutic proteins into ganglioside-rich cells.

Abstract
Peptide ligands are effective and specific vectors that can target cell surface receptors, and have shown great potential for targeting drug delivery vehicles. Often, materials used as drug delivery matrices are chemically synthesized and difficult to functionalize, which compromises their development as smart drug carriers. Here, we assemble carriers from a recombinant protein as a novel approach to overcome these limitations. We have previously shown that oleosin, a natural surfactant protein, can be engineered to self-assemble into spherical micelles, and that functionalizing oleosin with RGDS can increase cellular uptake in integrin bearing cells. Here, we investigated whether we could further enhance cellular by incorporating either a RGDS synergy peptide PHSRN or a cell-penetrating Tat peptide derived from human immunodeficiency virus (HIV). The resulting modified oleosins self-assemble into spherical micelles in aqueous environments. Spherical micelles made from oleosin can effectively encapsulate the hydrophobic chemotherapeutic drug paclitaxel (PX). After 15 hours, 350 nM PX loaded oleosin micelles equipped with both RGDS and Tat increased cell killing by twofold compared to free paclitaxel, and 1.2-fold compared to micelles made from RGD-oleosin alone. Micelles equipped with PHSRN alone does not facilitate cell killing compared to free paclitaxel, whereas micelles equipped with both PHSRN and RGDS increased cell killing by 1.1 fold compared to micelles with RGDS alone in 15 hours. Therefore, incorporating multiple motifs into oleosin is an approach for candidate for making a versatile drug delivery carrier.

Abstract
Protein engineering enables the creation of materials with designer functionality and tailored responsiveness. Here, we design a protein with two control motifs for its phase separation into micron sized liquid droplets - one driven by a hydrophobic domain and the other by oxidation of a disulfide bond. Our work is based on the plant surfactant protein, oleosin, which has a hydrophobic domain but no cysteines. Oleosin phase separates to form liquid droplets below a critical temperature akin to many naturally occurring membrane-less organelles. Sequence mutations are made to introduce a cysteine residue into oleosin. The addition of a cysteine causes phase separation at a lower concentration and increases the phase transition temperature. Adding a reducing agent to phase-separated, cysteine-containing oleosin rapidly dissolves the droplets. The transition temperature is tuned by varying the location of the cysteine or by blending the parent cysteine-less molecule with the cysteine-containing mutant. This provides a novel way to control protein droplet formation and dissolution. We envision this work having applications as a system for the release of a protein or drug with engineered sensitivity to reducing conditions and as a mimic of membrane-less organelles in synthetic protocells.
